Consider the quadratic function f(x) = 2x2 – 8x – 10. The x-component of the vertex is

The y-component of the vertex is

7

The discriminant is b2 - 4ac = (-8)2 – (4)(2)(-10) =

Step-by-step explanation:

Step one

Given the expression

we can solve for the The discriminant using the expression

Step two

from the given expression

the second term b=-8

the first term a= 2 and

the constant term c=-10

Step three

substituting all the terms into the expression we have

1.30

step-by-step explanation:

y-3=-3/2(x+4)
